Overview of Max Phase Niobium aluminum carbide Nb2AlC Max MXene Composite Material Nb2AlC CAS 60687-94-7

Niobium, often found in conjunction with tantalum minerals, is primarily extracted as a byproduct of tin and tantalum mining. Its chief ores include pyrochlore and columbite. Once refined, niobium becomes highly versatile, finding application in alloys, superconductors, and various high-tech materials.

Feature of Max Phase Niobium aluminum carbide Nb2AlC Max MXene Composite Material Nb2AlC CAS 60687-94-7

  1. Superior Strength and Lightness: When added to steel in small quantities (typically less than 1%), niobium significantly enhances the strength and toughness of the alloy while reducing its weight, making it ideal for aerospace and automotive applications.

  2. Corrosion Resistance: Like tantalum, niobium forms a passive oxide layer that protects it from corrosion, making niobium-based alloys suitable for use in harsh environments.

  3. Superconductivity: Niobium exhibits excellent superconducting properties when cooled below its critical temperature of about 9.2 K (-264°C or -443°F). This property makes it the primary material for superconducting magnets used in MRI scanners and particle accelerators.

  4. Magnetic Properties: Niobium is paramagnetic at room temperature but becomes strongly diamagnetic when cooled, meaning it repels magnetic fields. This characteristic is exploited in certain specialized applications.

  5. Ease of Fabrication: Despite its strength, niobium is easily formed, welded, and machined, facilitating its use in complex engineering designs.
